The Simulation of Vortex Modes in Twisted Few-Mode Fiber With Inverse-Parabolic Index Profile
The eigenmodes of an inverse-parabolic graded index fiber under torsion were investigated by using the finite element method simulation. These eigenstates correspond to orbital angular momentum modes except for the two polarized-vortex modes. The design of appropriate core parameters can lead to the...
